Abstract
Disclosed is a chip structure for an injection nozzle, which consists of a fluid structure and a bearing substrate. The fluid structure includes: a liquid spraying chamber, a spraying opening and a heat-resistance member. The heat-resistance member is engaged with the liquid spraying chamber to control the liquid injection from the spraying opening. The bearing substrate is connected with the fluid structure. The bearing substrate is thinned in order to form concave grooves serving as a heat-insulation chamber, the heat-insulation chamber corresponding to the heat-resistance member with respect to the bearing substrate, so as to reduce the dissipation of heat energy through the substrate, to reduce driving voltage power and then to enhance operation frequency and printing speed.
